I am setting up a system where M580 is Modbus Master data concentrator.
I have the Read_Var polling setup, my question is how do you guys handle Write_Var routines?
Do you just continuously write to the devices or do you have it set to just write when there is a command change? I can set it up to continuous write poll same as the read, however seems like there could be a chance of sending bad values??
Just reaching out to see how you handle this and possibly working examples.
I cannot use IO Scanning because that only supports Holding registers and I have 3x, 4x, 1x and 0x data that I am reading and writing and these devices have no logic.
Thanks
